Audio-technica System 9
A 4-channel frequency-agile wireless system, A-T's System 9 features sleek, contemporary styling with a stackable design. System 9 is available in handheld, headworn, guitar, lavalier, and body-pack configurations (other configurations sold separately). It offers 4 compatible user-switchable VHF channels (169.505, 170.245, 171.045, and 171.905 MHz).
Each System 9 outfit includes the ATW-R900a receiver and either a body-pack transmitter or handheld microphone/transmitter (other configurations sold separately). The ATW-R900a is a non-diversity, single-channel receiver with advanced dipole antenna design for extended operating range, improving operation by providing a ground element in addition to the usual signal element. The ATW-R900a also offers volume control along with AF Peak, RF, and Power indicator lights.
